Please review my following site structure.

Site1
-index
-about

Site2
-index
-about

I have written a c# code to publish the nodes.

// publish all the sub pages to create html / css
umbraco.BusinessLogic.User user = new umbraco.BusinessLogic.User(0);
Document post = new Document(nodeId);
post.Publish(user);
umbraco.library.UpdateDocumentCache(post.Id);

When I publish the "index" in "Site2" it publishes the "index" in "Site1" though in my code i provide the nodeid of site2->index to publish. Another thing that might clear my point, I am using Darren plugin to export the pages in html / css, so when my code publishes the "index" in "Site2" it publishes the "index" in "Site1", hence generate the html / css for "index" in "Site1". Any idea what to do with it?
